"static" includes
by Oliver Frommel 09 Mar '01

09 Mar '01

Hello, is there a way to include DTML files in a "static" way, i.e. preserving the same namespace the including DTML doc has. If you know what JSP does, this is including static (<%@include ..%>) vs. dynamic (<jsp:include ..>). In the first case the file is included before compiling, that means it is essentially just a simple text replacement or macro expansion. This would make breaking down my DTML documents to smaller parts easier, with the dynamic (that means <dtml-var ..> ??) way I'd need to change all variable references .. thanks --Oliver

[ANNOUNCEMENT]: New documentation
by Michel Pelletier 09 Mar '01

09 Mar '01

Hey folks, As I dropped earlier before the conference, I was going to make a number of important announcements. Well, for those of you who could not attend, here they are, as well as some other information that should be of interest to you. First off, as many of you know, New Riders is now publishing The Zope Book. The upshot of this is that the book is now under the Open Publication License (http://opencontent.org/openpub) The book has a new home at SourceForge, and you can go there and check the book out of CVS, add patches, bug reports, and request features. http://sourceforge.net/projects/zope-book/ And now for the *new* news, DC has commited to create a Zope Developer's Guide. This will be the authoritative text on building Zope components. It will cover Interfaces, Components, Persistence, Product Development, Security, Publishing, Debugging, and Testing. Its home is also at SourceForge, and it is also under the OPL. http://sourceforge.net/projects/zope-devel/ And last, but not least, we are writing yet another guide for you, the Zope Administrator's Guide. This guide will cover installation, building, clustering, database troubleshooting and repair, and many other very useful bits of information. Details are the same, SourceForge and OPL. http://sourceforge.net/projects/zope-admin/ As you can see, DC is commiting itself to providing full documentation coverage of all aspects of Zope: using, developing, and administerating. Please visit these projects and tell us what you think. The Zope Book is in its final stages of development, and the dev and admin guides are in their planning stages, so there's still a lot of work to be done. Finally, I'd like to mention that we have decided to start a weekly 'Featured Interface' article to be published in a as yet undetermined online publication, and Zope.org. This weekly article will feature one interface out of Zope, and prose and examples explaining the interface and how it can be used to complete useful projects. These articles will be oriented to be a very useful resource in conjunction with the upcomming dev guide, and will eventually be compiled into an upcomming, comprehensive interface reference for Zope. Well, that's it! (as if that's not enough ;). Stay tuned, and definately give us a hand if you feel the itch to help, we could use it. We are looking for bug-catchers, community editors, feature requests, pointers to existing documentation that can be included, and if you can write according to our guidelines and documentation process, authors. http://www.zope.org/DocProjects/developing Please send any comments or questions to docs(a)digicool.com, or any project specific comments to one of the above SourceForge projects. It was good to meet with many of you at the conference, and I was really pleased to hear lots of positive feedback about our recent documentation efforts. From here, it will only get better, and more fun! -Michel

Re: [Zope] system calls

As you already heard, you are not restricted by Zope security in ExternalMethods. Did you start Zope as "root"? In this case, it will switch to the user specified at installation immediately after it had bound the ports. If you did not specify anything, it will switch to the user "nobody". Maybe, the user switched to does not have permissions to access the external files. Dieter

"Authentication Window popping up" suggests that reading Brian's Zope security paper (-> zope.org) may help. Reading URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html may help you to understand when/why you use "mapping" as attribute for "dtml-in" or "dtml-with". Dieter

Almost surely, it is DTML source. More info: URL:http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html Dieter

What am I doing wrong? It means that you hit a place where the security restrictions introduced in Zope 2.2 have not yet been taken care of. You will find information on how to fix this problem in Brian's Zope security paper (-> zope.org) Put the problem in the Collector. Dieter

Acquisition Problem ?
by Richard Moon 09 Mar '01

09 Mar '01

Can anyone explain what's going on here - please ? I've got a dtml method 'mydtml_1' which processes a file uploaded via a form - like this <dtml-in "abcfile_read(REQUEST)"> <dtml-let abc_text=sequence-item> <dtml-unless "_.len(abc_text)==0"> <dtml-var mydtml_2> </dtml-unless> </dtml-let> </dtml-in> In the dtml method mydtml_2 I have some code like this <dtml-var expr="REQUEST.set('abc_text',external_method_that_returns_hello_world(abc_text))> <dtml-var REQUEST> <dtml-var abc_text> What happens is that the <dtml-var REQUEST> shows abc_text having the new value of "Hello World" but the <dtml-var abc_text> shows the value as it was in mydtml_1 Presumably <dtml-var abc_text> is acquiring the value from mydtml_1. Can anyone tell me why ? And how to get <dtml-var abc_text> to return the value I want i.e. "Hello World" ? This is Zope 2.2.1 (Note - if I do not put <dtml-var mydtml_2> inside the <dtml-in> and <dtml-let> constructs then it works as expected, e.g. <dtml-call "REQUEST.set('abc_text','Goodbye Forever')"> <dtml-var mydtml_2> will render "Hello World" ) Many thanks Richard Moon richard(a)dcs.co.uk

RE: [Zope] Acquisition Problem ?

You have an instance of variable-clobbering. abc_text is acquired from the dtml-let inside mydtml_1. You have set the value in REQUEST, but REQUEST is at the bottom of the list when variable names are looked up. This is explained on page 15 of the Document Template Markup Language Reference. Unfortunately, I can't find a link for it. Ok, I found it in the Zope Book http://www.zope.org/Members/michel/ZB/AdvDTML.dtml First section.
